Exemption
Reason *
Attach documentation from the manufacturer certifying the vendor selected is the only distributor/dealer/contractor for the products or services in question and/or holds the
production, unique capability, copyrights, trademark, and/or patent to the item, and check the following applicable statement(s):
Patent, copyright or unique design restrictions. (Sole Source)
Proprietary rights in technical data and/or product formulations (e.g. cleaning compounds, lubricating oils, paint, etc.), which can only be determined through
extensive laboratory analysis and examination. (Sole Source)
Only producer, such as utility supplier or construction material supplier, that will meet the specialized needs of the department or perform the intended function.
(Sole Source)
Direct replacement parts, equipment or supplies that must be compatible with original equipment already installed but available only from the original equipment
manufacturer. Most manufacturers have more than one dealer or distributor for their products. When this is the case, competition between dealers and/or
distributors may be possible, eliminating the “sole or single source” restriction. (Single Source)
When tests and/or demonstrations of equipment, supplies, part, etc. under actual operating conditions reveal superior quality, performance, design or other
characteristics in a brand product(s), which is available from only one source. Testing must be performed as often as practical. (Single Source)
Purchases for a brand product are to be made from one selected supplier, even though there are other suppliers that provide similar products. Options, such as
pricing, availability, servicing, have been vetted and a supplier has been chosen that best meets the City’s needs. (Single Source)
Maintenance, repair services or warranty which require specialized test equipment, procedures, and technical expertise available only from the original
equipment manufacturer or authorized/licensed dealer/field service representative. (Single Source)
The part(s)/equipment are required to permit standardization and operating efficiencies within the organization and the parts and equipment are only available
thorough a sole or single source. If competition is available, the parts and equipment must be competed. For brand-specific items, quotes should still be
obtained. (Standardization)
Other: None or some of the above apply. Provide detailed justification below.

This letter is to provide notification that Data Flow Systems®, herein known as “Company” with corporate
offices located at 605 N. John Rodes Boulevard, Melbourne, FL 32934, is the sole creator, manufacturer and
marketer of a group of systems and products, including the TAC II SCADA System, as well as Remote Terminal
Units (RTUs), Telemetry Control Units (TCUs), Hyper SCADA Server (HSS), HyperTAC SCADA Software, and the
Symphony Pump & Flow Management® technology. The company is also the sole source provider for all
associated support, repairs, service, and training for each of these solutions.
The company has nine (9) issued patents globally including patents governing wastewater collection flow
management and techniques, fluid flow management system and associated methods, fluid flow management
through a wastewater level manipulation system and associated methods, liquid level determination system
and association methods, liquid level determination system, valve malfunctioning detection system for a

Further, the Company’s family of products are designed and manufactured to provide users with unique

enabling effective, informed decision-making for corrective or preemptive action. The patented HT4 Mobile®
app is designed to have access to the software from the plant, field or office.
The patented Symphony Pump & Flow Management® technology coordinates the system-wide operation of
sewer lift stations for the purpose of reducing force main pressures and equalizing flow into a wastewater
treatment plant, which enables the ability to significantly reduce energy costs and provide a solution to daily
peak-flow issues
Among its portfolio, the Company is protected by the following US Patents: 8,594,851; 8,600,568; 8,983,667;
